2. A Suggestion at Tuyere of Blast Furnace Blast Furnace Arithmetic and Control Unit（DCS or Sequencer ） A Entrance（Cooling water） B Exit（Cooling water） ALARM（Leakage detected) • A－B（Flow rate difference) ＜Target（Normal） • A－B（Flow rate difference) ＞Target（Abnormal） High accuracy complies with reliable monitoring on cooling water leakage at tuyere! Damaged pipe, Cooling water leakage ⇒Steam Explosion Most Important Monitor Point

3. Since cooling water leakage is very important factor to monitor, very small leakage must strictly be measured. A company in Japan Flow rate range: 0-800 L/min Targeted differential flow rate: A－B＜３　L/min Differential flow rate: Below than 0.375% of full scale B company in Korea Flow rate range: 0-500 L/min Targeted differential flow rate: A－B＜５　L/min Differential flow rate: below than 1.0% of full scale *) Accuracy of Electro-magnet Flow meter: ±0.5% of reading Differential Flow Rate ～Strict Monitoring Standard～

4. Differential Flow Rate Monitoring ～Field Trial～ A Company – Result of Field Trial Targeted Differential Flow Rate: 0.375% of F.S. A (Entrance) B（Exit） A-B（DifferntialFlow rate） Result: 0.275%FS: Fully complied with severe monitoring standard!
